Abstract (en)
Disclosed is a hermetic compressor. The hermetic compressor includes a compression unit for compressing a refrigerant, a motor for providing a compression driving force of the refrigerant, a frame on which the compression unit and the motor are installed, a rotation shaft for transferring the driving force of the motor to the compression unit, and a journal bearing disposed on the frame such that the rotation shaft passes therethrough to rotatably support the rotation shaft, wherein the motor includes a stator fixed to an outside of the journal bearing and including a stator core, and a rotor including a body disposed outside the stator and rotatably installed such that the rotor rotates together with the rotation shaft by electromagnetic interaction with the stator, the stator core is coupled to a fixing member to prevent the relative rotation thereof with respect to the journal bearing, and wherein the fixing member fixes the stator core in a state in which the stator core is not moved in an axial direction and is coupled to the journal bearing to enable the stator and the rotor to be easily installed while the rotor of the motor is disposed outside the stator.
